Summary
Radiofrequency ablation (RFA) is a safe and effective treatment for accessory pathway (AP) mediated tachycardia. This study highlights RFA
Area of Science:
- Cardiology
- Electrophysiology
- Medical Devices
Background:
- Radiofrequency ablation (RFA) is a leading therapy for symptomatic, drug-refractory arrhythmias caused by accessory pathways (APs).
- A significant data gap exists regarding RFA outcomes for APs specifically within the Indian population.
Purpose of the Study:
- To evaluate the efficacy and safety of RFA for accessory pathway-mediated tachycardia.
- To establish a large Indian database for RFA in accessory pathway ablation.
Main Methods:
- Retrospective analysis of 434 patients (69% male) who underwent RFA for APs between January 1998 and May 2001.
- Data collection included patient demographics, arrhythmia type, procedural success rates, and complications.
Main Results:
- The procedure was successful in 97% of 425 attempted cases.
- Common findings included Wolff-Parkinson-White (WPW) syndrome (73%) and concealed APs (27%).
- Complications were rare, with three cases of pericardial tamponade successfully managed; no deaths occurred.
Conclusions:
- Radiofrequency ablation is a highly effective and safe treatment for accessory pathway-mediated tachycardia.
- RFA is particularly beneficial for pediatric and young adult patients, offering an alternative to long-term medication.
- This study contributes valuable data on RFA outcomes in India.
